Natural convection in enclosures with localized heating from below and symmetrical cooling from sides
Orhan Aydin,Wen-Jei Yang +1 more
TL;DR: In this paper, a two-dimensional, rectangular enclosure with localized heating from below and symmetrical cooling from the sides has been numerically investigated and the results showed that the average Nusselt number at the heated part of the lower wall, \overline Nu, was shown to increase with an increase the Rayleigh number, Ra, or of the non-dimensional heat source thickness.

Mehmet Cem Ece,Elif Büyük +1 more
TL;DR: In this article, the authors considered the effect of the orientation and the aspect ratio of the enclosure and the strength and direction of the magnetic field on the flow and temperature fields in an inclined rectangular enclosure heated from one side and cooled from the adjacent side.

Heat transfer by free convection across a closed cavity between vertical boundaries at different temperatures
TL;DR: In this article, the authors considered the two-dimensional convective motion generated by buoyancy forces on the fluid in a long rectangle, of which the two long sides are vertical boundaries held at different temperatures, and determined the rate of transfer of heat between the two vertical boundaries.

Numerical study of natural convection in an enclosure with localized heating from below—creeping flow to the onset of laminar instability
K. E. Torrance,J. A. Rockett +1 more
TL;DR: Torrance, Orloff & Rockett as discussed by the authors made an analytical study of the natural convection induced in an enclosure by a small hot spot centrally located on the floor, and solved the equations of fluid flow in axisymmetric cylindrical coordinates with the Boussinesq approximation.

Experiments on natural convection in enclosures with localized heating from below
TL;DR: In this paper, an experimental study was made of the steady-state natural convection induced in enclosures by a small hot spot centrally located on the floor, which was made visible by adding metaldehyde dust particles and illuminating them with an intense light beam.
